My MSPNP 90-93 Thread
Check your timing again. If you are running Jerry's basemap and the car will not rev, but it revs if you advance everything 10 degrees, something's wrong with the timing on the car itself. Check the orientation of the timing belt, ensure that your TDC marks are *actually* TDC marks (pull the plugs, spin the motor to TDC, compare marks), and ensure the timing belt is set correctly.
2. He dicks with his timing and the car runs better
3. He sets his timing up as it should be, and the car doesnt run
Logic tells me that if the basemaps are correct (which they are, 99% sure), then something with his car isn't correct. If your timing marks are off, or you are using the wrong mark, then you aren't going to be able to time the car right. Dollars to donuts, he's got the timing fucked up.
Common on older engines for the harmonic balancer to get sloppy, hence incorrect timing values would be observed compared to actual. Would be odd for a new engine to have that problem, but if you've followed the timing set up in the manual correctly, then the timing problem is mechanical and not electrical. Are you positive you set the trigger angle correctly? If so, it's probably time to do the TDC dipstick test to see how you need to proceed.
Like the others have said, your timing is off. If your harmonic balancer shows visible signs of wobbling, replace it ASAP. It is quite likely that the timing marks on the balancer have slipped far enough that they're giving you the wrong reading.

yepp, it does wobble...... didnt think much of it at first.... its not bad but its noticable.... im going to call FM today, that would explain why the car works when the timing is advanced 20 degree's?
but its works fine with the stock ECU ?
or was i still just way off and the stock ECU didnt really give a **** ?

ok well pulled it off and layed it next to the other one i had and put the alignment holes in the same place and then looked and the timing marks and its off about 2 and a half inches...... Bad ? ....... well i found my problem then.
I had the same problem. My timing was only of by 16 degrees. I did not find out until the pulley came apart at 7,000 RPM. that was fun.
